Affix polyfunctionality in French deverbal nominalizations

This article investigates the semantic polyfunctionality of affixes, i.e. their ability to serve a variety of distinct semantic functions. Based on the analysis of a sample of 3,091 deverbal nouns ending with 46 different suffixes in French, the study examines the diversity of semantic functions realized by deverbal suffixes, the distribution of these functions across suffixes and the relationships that may exist between different functions. It appears that polyfunctionality is widespread among French deverbal suffixes and involves a large number of semantic functions, with highly variable realization frequency. Several fundamental aspects of affix polyfunctionality are further highlighted. A probabilistic analysis shows that polyfunctionality can be driven by non-arbitrary semantic associations between functions. A hierarchy of functions can also be postulated depending on whether they can be instantiated by monosemous or only polysemous derivatives. In addition, polyfunctionality appears to be inseparable from rivalry relationships and to determine the degree of rivalry between affixes. Overall, the study illustrates that affix polyfunctionality is governed by systematic organizing principles whose ramifications touch on lexical ambiguity and morphological competition.
